GASOLENEENGINE.

Specification of Application filed August 1,

useful Improvements in Gasolene-Engines;

and I do declare the following to bea full, clear, and exact description of the invention, such as will enable o'thers skilled. in the art to which it appertains to make andl use the same.

This invention relates to internal combustion engines, and more particularly to that class of said engines y in which liquid fuel is used for causing the explosion.

= The object of the 'invention is to provide means whereby the engine may be started with a volatile liuid such as naphtha or gasolene and run until the explosionchamber becomes sufficiently heated to volatilize heavier liquid such as kerosene or denatured alcohol, whereby the -engine may be run as efficiently upon the same/amount of a cheaper grade of kerosene or heavier oil that was required of gasolene orthe lighteroil, and accomplishes the same result, thereby efl'eeting a considerable saving in the expense or cost of the fuel as heretofore used.

Efforts have been made heretofore to use the heavier and cheaper liquids with a greater or less degree of success. I havediscoveredthat by properly mixing the proper parts of kerosene, air and water, such mixture can be used in an ordinary en ine with great success, as it does not injure t e engine any more than does a lighter and more costly liquid.

with these and other oppas in View, the

`invention consists of certain novel features ol" construction, combination and arrange ment of parts, as'will be more fully described and particularly pointed out inthe appended claims. I'

In the accompanyingdrawings, Figure 1 is a'diagramniatic view partly in section showing a portion of an internal combustion engine provided with one means l'or feeding diil'erent' kinds of fuel thereto. Fig. 2 is an end. elevation oit an engine provided with a slightly modiiied l'orm of means for supplying vfuel thereto.

.inthe embodiment illustrated an 'engineJ cylinder 1 is shown, which may be of any Letters Patent. Patented May 25, 1909.-

"ordinary construction provided with a reservoir or earbureter 2, and having` a head 1a provided with a spring pressed inlet valve 1b.

Communicating with the reservoir 2 are two pipes 3 and 4,' which are provided with three-way valves v5 and 6, respectively. Connected to communicate with the pi e 3 are municates wit 1 the gasolene tank 9 and the other with the kerosene tank 1U 'and a threeway valve 5 is arranged at the junction of the pipes 3, 7 and 8, and is operableto bring one of the pipes 7 or 8 into communication with the pipe 3 when desired, 4and to shut oll the other pipe. l'

A pump 16 is connected with the supply pipe 8, and is adapted to be operated by the engine in any ordinary manner for the purpose` of conveying fuel from the tank 10 to the reservoir 2. Connected to communicate with the pipe 4 are two pipes 11 and 12, the pipe 11 communicating with the gasolene supply tank 9, and boing designed to return return pipe for returning the kerosene to sai d tank 10. A threeway valve 6 is arranged at the junction oi pipes 4, 11 and 12, Aand is operable to bring either of the pipes 11 or 12 A pump 15'is connected with the supply pipe 7 and is operated by the engine in t ie same manner as the pump 16, and is adapted to Voir 2.'

The ipe 4 extends into the reservoir 2 referalgly to a point about midwa the ieig'ht thereof and constitutes an overA ow to permit the oil when it reaches a predetermined point to be returned 'to its source of `supply when the pump is in operation.

In the drawing the valves are shown in the starting of the engine.

outlet 26, arranged at the normal liquid level of said reservoir, and the valve oi' this outlet has a stem 27 extending through the outer end of the reservoir 2 and is provided with a handle for operating the outlet` valve to vary the amount of oil to be fed therethrough.

A pipe 28 of commratively large diameter E surrounds the valve 1b at one end and the two supply pi es 7 and 8, one of which come' gasolene from the reservoir 2, after it reaches a predetermined point; the other 'pipe 12 is a into communica tion with pipe il, as desired.

position in which they are turned at the' force the fuelirom the tank 9 to said reser l The reservoir 2 is provided with a valved other end thereof is open to the atmosphere at a point somewhat remote from the inlet A nozzle 29 opens from the valved valve 1b. oil outlet- 26 into said'pipe 28, and a nozzle 3() connected with a water supply pipe 31 also opens into said pipe 28 at a point between 1 the open or air inlet end and the oil nozzle. This pipe 31 is preferablyA provided with a stop cock 31 for `regulating the supply of water to be fed through the nozzle 30. When the engine is in operation and the piston 32 moves inward it creates a vacuum in said cylinder which opens the valve 1b against the tension of the spring, and the opening of this valve causes suction in the pipe 28 and draws therein oil through the nozzle 29, water through the nozzle 8O and air through the open outer end of the e 28, and these in# gredients are thoroug y mixed and commingled in the pipe 28` before entering the y combustion chamber of the engine.

lVhen it is desired to start the engine, the cock 51.l being closed, the three-Way valve 5 is operated to cut off communication between the pipe 3 and the pipev 8, and to bring -the pipe 3 into communication with the gaso' lene supply pipe 7, (as shown in Fig. 1) and the pump 15 being in operation, the gasolene is forced through said pi e 7 into the reservoir 2 and passes outt irough the valved outlet 26 into the combustion chamber in the usual manner. The overiiow of gasolene passes down through the pipe 4 through the pipe 11 back to the tank 9, the valve 6 having een operated to cut off communication with the pipe 12. After the explosion chamber has been heated to the pro er degree by the explosion of the lighter fue therein the cock 3l is o ened and the three-way valve 5 is opera/tet to shut off the supply of the lighter fuel and to turn on the sup ly of the heavier fuel, which ilows through t e pipe 8 into the pipe 3, and from thence into the reservoir 2, and after reaching a predetermined overflow -point passes back through the pipe 4 into the return pipe 1'2 which conveys it to the tank 10, the valve 6 having been previously operated to cut off communication of the pipe 4 with the pipe 11. The return pipes 11 and 12 are provided with stop cocks 17 and 18 respectively for controlling the passage of the excess of fuel therethrough as 1t is being returned to the tanks 9 and 10 respectively.

Cross pipes 13 and 14, connect the pipes 7 and 1.1, 8 and 1,2, respectively, and are rovided with stop cocks 13 and 14. Ihese cross pipes 13 and 14 are designed to convey the gasolene or kerosene, as the case ma be to its return pipe and back to the tan when its respective pump vis in opera tion and the valve 5 is turned to cut it off and the cross Vpipe 13 is opened and the pump 15 being continuously in' operation, the'gasolene is .pumped through pipes 7, .13 and 11 back to tank 9. When valve 5 is turned to bring pipe 7 into communication with pipe 3 and cut off pipe 8, the cock 13 is closed and cock 14 in pipe 14 opened "and while the gasolene is pumped into reservoir 2, the kerosene circulates through pipes 8,14 and 12 back and to tank 10 and continues to so circulate until the cock 14 is closed and valve 5 opened to turn the i kerosene into the tank or reservoir 2. By l this construction the pumps 15 and 16 may i remain always in operation during the runl nino of the engine.

l Iithsmall engines one of the pumps may l be dispensed with and the supply of gasolene or lighter oil can be placed 1n a small vessel 21, which is located above the reserity. By the time the oil in the vessel 21 has been consumed the engine will be sufficiently hot for the use of the heavier grade of fuel, when the valve 22 in the supfply piple 23 is turned and the supply of fuel rom t e tank 24 is permitted to enter the engine, as above described, and the surplus is returned through the pipe 25.

or less amount of resi ue is apt to be deposited in the engine. It is therefore preferable to cut off the supply of the heavier grade a short time previous to the shutting down of the engine and to turn on the lighter grade ofv oil, which will prevent the deposit from the heavier grade of oil, permitting it to be carried in through the exhaust and thereby leaving the engine pen fectly clean for starting up.

Erom the foregoing description, taken in connection with the accompanying drawi'ngs, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

V arious-changes in the form, proportion, and the minor-details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.
